About Ergometar
We're building the future of indoor rowing.
Our Story
Ergometar was born from a simple frustration: rowing on a Concept2 is incredible exercise, but training alone gets old fast.
We set out to build a platform that makes every session count — whether you're racing a rival across the globe, chasing a personal best, or just trying to maintain your daily streak.
Built on Elixir and Phoenix — the same technology that powers real-time systems serving millions — Ergometar delivers the responsive, reliable experience that competitive athletes demand.
